摘要

针对大量非色唯一图

利用图的伴随多项式

最小根及其特征标的性质研究了一类稠密图的色性:完整刻画了该类稠密图的色等价图类

并给出了其色唯一的充要条件.这为图的色性研究提供了新的工具和方法.

Abstract

In allusion to a large number of non-chromatically unique graphs

the chromaticity of a class of the dense graphs is studied by applying the properties of graph′s adjoint polynomial

minimum roots and character features.The chromatically equivalent classes of the dense graphs are completely characterized

and the chromatically unique sufficient and necessary condition of the graphs is obtained.The new tools and methods are provided for the chromaticity research of graphs.
